リクエストが有効であっても、別のエラーが発生してストリートビュー画像を表示できない場合、Street View Static API はエラーに応じて、ストリートビュー画像の代わりにテキストまたはエラー画像を返します。このようなエラー状態の例としては、アプリケーションが使用量上限を超えた場合などがあります。

This guide explains each error message, and provides further\ninstructions for resolving errors.\n\nInvalid requests\n----------------\n\nIn the case of an invalid request, the Street View Static API returns\nan HTTP `4xx` status code and a message describing the\nproblem. Below are examples of such error conditions. Note: This is not\na complete list of the possible errors. Please check the actual error code\nand message returned by the API for details of specific problems.\n\n| Example of error condition | Status code |\n|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|-------------------|\n| The request includes an invalid parameter, or a required parameter is missing. For example, the `size` parameter is not within the expected range of numeric values, or is missing from the request. | `400 BAD REQUEST` |\n| The API key included in the request is invalid. | `403 FORBIDDEN` |\n\nErrors that prevent a street view image from being displayed\n------------------------------------------------------------\n\nIf the request is valid, but another error occurs that prevents the street view image from\nbeing displayed, the Street View Static API returns either text or an error\nimage instead of the street view image, depending on the error. An example of such an error\ncondition is when the application exceeds its\n[usage limits](/maps/documentation/streetview/usage-limits).\n\nFigure: An error image displayed instead of a street view image\n\n### Errors related to API keys and billing\n\nIf you use the Street View Static API without an API key, or if billing\nis not enabled on your account, the page displays an error image instead of a\nstreet view image, with a link indicating the type of error. For example\n\"g.co/streetviewerror/key\".\n\n| Keyless errors and solutions ||\n|---|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|\n| | You are using the Street View Static API without an API key.
